Combine the tandoori masala, garlic ginger paste, kasoori methi, naga (if using) and oil. Stir to combine. You want a nice slurry. Taste. Yes. I know it's a little strange but it's actually quite tasty. If it is well seasoned you are good. If it seems like it could use a bit more salt then add the salt as well.
Combine the tandoori masala mixture with the chicken. Make sure the chicken is well coated. Don't use your bare hands for this. Tandoori masala has food colouring in it. It will stain badly.
Set aside (refrigerated) for up to one day. You can go within 30 minutes. After 12 hours it will be fully brined. Any longer and you are just letting the food colouring penetrate a little further. For the record the chicken in the pictures was marinated for about 30 minutes.
Ideally you can grill the chicken over charcoal until it hits an internal temp of about 150F for white meat. 160F for dark meat. You want it a little underdone because it will cook some more when you fire your pizza.
If you are doing it in the oven simply roast in a 400F degree oven. Flip the chicken at around the 10 minute mark and cook to the recommended internal temperatures. You don't need to worry about trying for char for this to work.
